Our research, published this week in Nature Nanotechnology, describes a new type of graphene-based detector that overcomes some of the limitations of conventional THz technology. The device exploits the very unique optical and thermal properties of graphene to achieve a noise-equivalent power that rivals the best available THz detectors, and a speed that far exceeds that of bolometers and pyroelectric detectors. Even more remarkable is that the spectral responsivity spans an unprecedented range of frequencies, from near-infrared down to terahertz.
